Sexy Whatever Outfit

Making a sexy outfit, usually for women, modeled on something that, barring Fetishes, isn't really sexy on its own (say a famous Pimped-Out Dress or a deck of cards). It doesn't matter what it is, someone will try to make attractive clothing based on it.

This shows up in fiction, but is also Truth in Television when it comes to Cosplay and Halloween outfits (like in the picture). Yet they aren't sold on the kinky sites, but mainstream stores. This is because most of these outfits (and sources) tend to not be outright obscene, so most examples of this tend to fall into "PG" territory.

Film

Discussed in Mean Girls, where Cady is the only girl at the party who dresses in a non-sexy Halloween costume. "In Girl-World, Halloween is the one time of year you can dress as an absolute slut and get away with it."

On the battlefield of the war between the hippies and the frat orcs, fighting on the side of the hippies may turn up battles against a Naughty Sorority Nurse. She is described as being drafted as a medic for the frat orcs because she showed up in a sexy nurse outfit, and she was only in THAT outfit because everyone already took the outfits for the sexy stewardess, the sexy pirate, the sexy referee, the sexy rollerskater, the sexy plumber, the sexy train conductor...

In the 2011 Halloween event, the sorority orcs turned their sorority house into a haunted house. While they have been turned into various monsters along the way, each one is described as wearing a sexy costume of a randomly generated, increasingly-esoteric profession. Such as a sexy astronaut, a sexy dentist, a sexy clothier, a sexy patent attorney, a sexy feminist blogger, a sexy chemical engineer, a sexy lexicographer, a sexy rat catcher...

In Misfile, Ash claims that girls use Halloween as an excuse to dress up as whores using these kind of costume. Emily's rebuttal is that it's the one time of year that women can dress up like that and not actually be accused of being whores, and doesn't think it's a fair accusation anyway. Given that she wore a sexy nurse outfit the previous year and most of the women at the following party wore something similar, though, Ash did kinda have a point.
